A TTUHNEYS specti-vely, bearings 27 being disposed in the sides of the said openings 25 and 2G, axles 28 being Journaled in the said bearings and vancs 29 being mounted on the axles 28.

.from the top and bottom of the keel'members to the corners of: the Yanes. ltlach of the upper 'vanes 2S) is connected with a vane 29 immediately below it, b v means of cords 33. By this'nieans, when one of the lower vaiies is operated, the upper vane mores therewith. At one side of each of the axles 28 of the lower Yanes 29 there are secured sprocket wheels EH, the sprocket wheels being connected together' by sprocket chains respectively, there being an. additional sprocket chain 3G mounted on a sprocket wheel' secured to a shaft journaled on one of the struts 14, tliespijocket chain 3G being also connected with the sprocket-wheel it secured to the shaft '28 of the lower vane 2t) which is at t-he front of the airship. It will therefore be seen thatwhen the sprocket wheel 37 is rotated, by means'of a crank Bt), all the vanes 2t) will be moved simultaneously Iin the saine direction.

'- The fronts of the planes 15 and 2t are cut.

away to form concave edges 40 atthe bow ot the airsliip. Secured to the frame menibers 18 and 23, at the bow ot'vthe airship,

are cords 41. lTwo of these cords Jet are secured immediately infront of the planes respectively, the cords diverging rearwardly and being secured vto the -planes at their sides. There are also additional cords 42.

which are secured at the saine point where the cords 41 form angles, 43, these cords L12 diverging downwardly and rearwardly re\' spectively, relatively to the plaiies. l'i'ight material 411 is secured to the* cords 'll and is disposed under the cords ft2, thereby forming heads, which extend rearwardly of the l'ront concave portions il() ot' the aeroplane. The

Lipper portions ot the heads are open, and

the heads are also open at their rear. The

heel members 3.0 are disposed immediatelyi u the rear of the heads formed by thematerial 40 disposed over the cords |1 and t2,

In the upper plane 2l there are two transverse openings '15, which are separated by transverse, traine members 4G, a. shaft -t'i' being journaled lo g'itudinally ot the airship in the rear opening 5, there'heing propeller 4.8 mounted on the .said shaft v- In the lower plane there is a. transveise opening ftf), there lbeingl .two shafts 5'()V journ'alcd in the said openingJongitudinally ot the airship, propellers 51 being mounted on tandem. 'As iny airship isunusually long,

it will be necessaryto supply an extensive rudder surface, and in order to obviate any ditliculty which is occasioned by ruddeis.

which are of great length, I have .provided the two rudders as 'shown in thedrawings, These rudi'lers are operated by independentcables, which run to the sides of the -aeroplane and then are brought downwardly to be operated by levers in the` car. These operating levers are disposed side by side,v

and may be moved together or independently of each other, at'the will of the operator. They may also, when desired, be moved with the tiller 12.

The planes of my airshi'p ai'e of unusual length and the vanes are disposed in the central openings. When these vanos are open,

the planes with the central vopenings serve.

as a parachute to delay the descent of the airship, should its operating mechanism be impaired. lVith the vaiies it is possible for the operator to lift his ship gradually and steadily without any pitching, such as takes place with the forward plane of the vWright or Curtiss machines when used to cause an ascent or descent. It will iilso be undersood that as the vanes are disposed in the center of the planes, they will canse the .--airship to move more evenly than in otlierconstructions. This i.v` especially true where -tl1e vane may come in contact with lateral airv currents, for when the Avanos are disposed together in the center of 'th-,e planes, they willall come in contact withtthese aircur- ,rents at sul'istantially the same time or in 4case. they should not, no great. injuryv can be done, as pressure exerted ont-he vanes respectively'- will be. distributed evenly throughout the planes. It' will understood thatC while all these advantages are obtained by the construction which I vhavedescribed,` with the.' vanes disposed in the central 'openin- I 'lit is possible to prevent any sliding oil' ofthe wind by means ot the rudder members which are secured to the valles, the rudder members being dis- `posed longitndii'ially of the aix-ship immedi- 'a'.tcly in the iear of the heads.

.Ey mounting. the rudde'rs tizi-5.;'inde-pendeutly of each other, not only is itfpossible to more one rudder indepeiulently of the other to steer the ship, or bothrudders together also be y isa when a quicker turn is desired, but it is also possible to movethe rudders in opposite directions, so that they will serve as brakes and will check the movement of the airship through the air.

As the heads are constructed, they are secured firmly relatively to the frame members 18, 23, the planes 15, 24 being cut away as has been described, to forni openings` through which the air, cnt by the heads, may be driven.

Having thus described my invention, I claim as new and desire to secure by Letters Iatentz.

l. In an airship a plane having a transversely disposed head member, the front of the said head member projecting forwardly of,` the plane and substantially in alinement t erewith, the rear of the member being spaced from the plane and extending rearwardly below the front of the plane to permit the air to pass between the plane and the head member.

2. In an airship a plane the front edge of the plane being cut away, and a transversely i disposed head member spaced from the plane to permit the air to pass between the plane and the head member, the front ofl the head member being disposed in front of 4the bow of the plane with the rear of the head member extending rearwardly below the said bow.

3. In an airship a plane and a, head, open at the top, and rear, disposed in front of the plane, the bottom of the head at the rear thereof being lspaced from the plane and normally disposed below the level of` the plane to permit the air to pass between the rear o'fthe head and the plane.

4.111 an airsliip, a plane, the sides of which converge rapidly at the bow, the sides converging slowly rearwardly forniiiig an elongated tail, two members which diverge rearwardly from a point in front of theplane and which are secured thereto, another member which extends downwardly and rearwardly from the' said point, and inatcrial disposed against the sides ot the menibers to form a head, open at the top and rear.

."i. In an airship a plane the how ot' which has a ciitsaa'av portion, two nienihers which diverge,rearwardly troni a point in front of thc bow of the plane, another member which extends downwardly and rearwardly from the said point to a' point below the plano, and material disposed against the sides of thc members to forni a head open at the top and rear.

(3. In an airship two planes, one disposed `over the other, each of the planes having a ing, vanes disposed in the openings and piv-' oted relatively to the planes, the vanes being disposed 1n two series one series in each of the openings, and means connecting the upper and lower vanes in pairs.

9. In an airship, two pla'nesdisposed one over the other, eachhaving a cent-ral opening, vanes disposed in the openings and pivoted relatively to the planes, the varies being disposed in two series, one series in each.

of the openings, means connecting the upper and lower va-nesl in pairs, and means adapt-` ed to operate one' series of varies simultaneously.

'10. In an airship, two planes disposed one over the other, each having a central opening, varies disposed inV the openings which are pivoted relatively to the planes, the vanes heilig disposed in two series, one series in each of the openings, means connecting the upper and lower vanes in pairs, and keel members Secured to the vaines.

11. In an airship, a plane having a central opening, a vane disposed in the open# ing and pivoted relatively to the plane, a

keel member disposed ,longitudinally of the airship and secured to the vane, and a head disposed at the bow of the airship and in longitudinal alinement with the lcecl""mein ber. I

12. In an airship, two planes, one disosed over the other, there being an opening 'in cach Vot the planes, a propeller disposed in one of the openings, and' two pro| )ellers disposed in the other opening, a main4 shaft, means connecting the said two propeller-s with the main shaft iinlepcndcntly olr each other, and ineans connecting the first-nientioned propeller with the said two propcllers.

In testimony whereof I have signed my.

naine to this speciticatit'in in the presence of two subscribing witnesses.
